I want to interface my Arduino to a ConnectOne miniWiFi module via TTL serial. The wifi module requires 3.3V levels. Can I just use two MOSFETS as described in the Philips I2C document? (Serial is different protocol but it seems generic enough…)

Or … is there a better,easier or otherwise generally accepted way of doing it?
